J'OHNNY W. YARTZ BYZQ H\S ATTORN Y United States Patent 3,082,964 SINK CONNECTION SUPPORT FOR WASTE DISPOSAL APPARATUS Johnny W. Yartz, Anchorage, Ky., assignor to General Electric Company, a corporation of New York Filed Oct. 3, 1960, Ser. No. 60,051 9 Claims. (Cl. 241-1005) This invention relates to apparatus for the disposal of waste material wherein garbage and other kitchen wastes are comminuted in the presence of water by power driven comminuting means to a flowable mixture and the resultant mixture flushed to the waste disposal system of the house; and is especially applicable to such disposal apparatus which is connected with the drain opening of a kitchen sink which opening serves as an ingress opening for the admission of the waste material and water to the grinding apparatus.

This invention contemplates the provision in apparatus of this kind of improved means for attaching the apparatus to and supporting it from the sink in proper relation with the sink drain opening and incorporating means for isolating from the sink and hence from the kitchen the vibration incident to the operation of the apparatus and thereby reduce materially the noise usually associated with Waste disposal apparatus. This invention further contemplates the provision of such means which includes in its construction features which provide for the quick assembly and disassembly of the comminuting apparatus with respect to the sink.

Briefly stated, in accordance with one aspect of this invention, I provide a food waste disposer having a comminuting housing which has an upper inlet opening which is intended to register with the sink drain opening and afford an ingress opening for the waste material and water introduced through the sink opening. I also provide a supporting sleeve for the housing and its associated comminuting apparatus arranged to be mounted in the drain opening in supporting relation with the sink. The comminuting housing with its associated power operated grinding means is supported from the sleeve, so that the upper end of the housing is in concentric relation outside of the sleeve, by a series of attaching means circumferentially spaced about the meeting end portions of-the housing and sleeve. The attaching means provides for support of the housing from the sleeve; vibration isolation of the housing from the sink; and provides for ready assembly and disassembly of the housing with respect to the sink. In one form of this invention, each attachment means includes an inverted hook-shaped member attached rigidly to the upper end of the housing and having its hooked end seated on and supported by a yielding mem ber formed of an elastomeric material supported on the lower end of the sink sleeve. In another form the hook members and yielding members may be reversed, that is, the hook members may be attached in an upright position to the sink sleeve, While the resilient members are fixed to the housing so as to engage the hook ends to support the housing. In either case, the elastomeric members provide for shifting movement of the hook ends which engage them so as to permit the housing to have universal movement to a limited extent while isolating the housing from the sleeve and sink to reduce the transmission of vibrations and noises from the housing to the sink.

Preferably the upper end of the housing will be spaced from the sleeve and a resilient sealing ring attached to the housing will be interposed to close this space and thereby effect a radial liquid seal between the resiliently mounted housing and the stationary sleeve.

The connection means of this invention will permit quick assembly of the disposal housing with the sleeve merely by elevating the housing into telescopic relation with the lower end of the sleeve and to a point where the hook ends and their seats are separated in the vertical direction, turning the housing slightly to align the hook ends with the seats, and finally allowing the housing to fall into its operating position in which it is to be supported from the sleeve by the hook ends which are then in engagement with their seats. The sealing ring will be attached to the disposal housing so that when the housing is elevated for attachment with the sleeve, the ring will be moved automatically into sealing relation with the sleeve.

For a more complete understanding of this invention, reference should be had to the accompanying drawings in which: a 7

FIG. 7 is a fragmentary vertical sectional view of waste disposal apparatus embodying another form of this invention; and

FIG. '8 is a vertical sectional view taken through the line 8-8 of FIG. 7.

Referring to FIGS. 1 through 6 inclusive of the drawings, this invention has been shown in one form as apcylindrical tubular casing or housing 1 enclosing a grinding or shredding chamber 2 at the bottom of which the comminuting or shredding of waste material takes place. Any suitable-shredding means may be used at the bottom example the shredding means may be used which is described and claimed in the United States Patent to H. J.

Macemon No. 2,828,083, dated March 25, 1958, and as signed to the General Electric Company, the assignee of this application. Briefly, the grinding means comprises a stationary shredding ring 3 which is provided with cutting surfaces 4 and with a plurality of apertures 5. Coacting with the shredding ring 3- is a material impelling flywheel 6 which is provided with impellers 7 arranged when the flywheel is rotated to impel the waste material against the shredding ring 3 to comminute the material into a fine mass. It will be'unde'rstood that during this opera' tion water will be caused to flow down through the housing 1, and that eventually the Water and the comminuted material constituting a flowable mass will beimpelled outwardly through the apertures 5 into a drain chamber 8 which drains into a drain line 9 which in turn is connected with the sewer system of the house. The flywheel 6 is driven by a suitable electric motor 10.

The upper end 11 of the housing 1 constitutes an opening through which the waste material and the water is supplied to the housing 1 from the drain opening 12 pro.- vided in the household sink, the bottom wall of the basin .of which is designated by the numeral 13.

The means arranged in accordance with this invention material of which the n'nglS is made.

Each support 33 is formed to be yielding to some ex V tent and for this purpose it is made of an elastomeric mafor supporting the disposal unit from the wall 13 to vibration insulate the unit from the sink and hence from the house in which the sink is installed, comprises a cylindrical tubular sleeve 14 which is arranged to be inserted down through the sink opening 12 and at its upper end is pro vided with an outwardly extending circular flange 15 adapted to overlie the annular marginal edge 1-6 of the drain opening 12, as shown in FIG. 1. Preferably and as shown the marginal area 16 will be slightly depressed from the bottom wall 13. The lower end of the sleeve 14 is provided with an inturned flange 17 which will support a suitable sink stopper (not shown), for example as shown and described in the United States patent to F. W. Moore No. 2,787,423 dated April 2, 1957, and assigned to the General Electric Company, the assignee of this application.

The sleeve 14 not only functions to conduct the waste material and water to the housing 1 but it also constitutes the sole supporting means for the housing 1. For the purpose of supporting the disposal unit thesleeve 14 itself is rigidly secured to the bottom wall 13 of the sink. This is accomplished by a metal mounting ring 18 which encircles the depending sleeve 14 and is provided with a series of spaced integral bosses 19 depending from the ring 18 and bolts 20 threaded into the bosses; preferably the bosses 19 and associated bolts 20 will be spaced at uniform intervals around the circumference of the ring 18 (three being provided in the form of the invention illustrated spaced 120 apart). 'The ring 18 with the bolts 20 is supported fromthe sleeve 14 by means of a snap ring 21 which is supported on an outwardly facing circular bead 22 formed in the sleeve. The bolts 20 function to clamp the flange 15 to the annular wall 16 ofthe sink by means of a clamping ring 23 encircling the sleeve, it being understood that when the bolts 20 are screwed upwardly they will sandwich the annular wall 16 between the flange 15 on the sleeve and the ring 23; preferably a ring gasket 24 encircling the sleeve will be inserted between the bottom of the sink and the clamping ring 23.

i The mounting ring 18 not only functions to rigidly secure the sleeve 14 to the sink, but it also constitutes the means for attaching the disposal unit to the sleeve 14. F or this purpose a metal support ring 25 is positioned to encircle the upper end portion of the tubular housing 1. It is, as shown, mounted in a circular recess 26 provided for it in the upper end portion of housing 1, the support ring preferably being provided with a slit 27 (FIG. 2) so that the ring may be sprung into the recess.

The assembly of housing 1 and its associated comminuting mechanism, and the support ring 25 is arranged to be secured to the mounting ring 18, and for this purpose I have" provided a series of connection means 28 (three in the embodiment illustrated) spaced about the adjacent end portions of the'housing 1 and the sleeve 14; as illustrated inFIG. 2 three connection means 28 are provided spaced 120 apart. 7

Each connection means or set comprises an inverted dis torted U-shaped or; inverted hook-shaped member 29 (FIGS. 3 and 4) having the lower end. of its'long leg rigidly secured to the support plate 25' as by screw fasten ing means 30. The nexus 31 of the U or hook member 29 extends circumferentially in the direction of'the ring 25, and this portion terminates in the downwardly extending short leg 32 of the hook.

Y The short legs 32 of the hook members are supported by means of. the mounting'ring 18 attached to the sleeve 14, and for this purpose the attachment means 28 further comprise a yielding cylindrical support 33for each hook end 32., Each'support 33 is mounted in a cup 34 supported by and depending from the ring 18; preferably the cups 34 will be "formed of and depressed from the terial. Each support 33 is provided at its upper end with a flange 36, and also is provided on its exterior wall with four integral, flexible spacing ribs 37 extending vertically on the outer walls from top to bottom and which function yieldingly to space the cylindrical body 33 from the side walls of its cup 34-; the cylindrical support 33 is mounted with its vertical axis substantially parallel with the vertical cups of the housing 1 and sleeve 14.

Secured to the flange 36 of each elastorneric body 33 as by bonding or cementing or gluing is a metallic depressed seat 38 shaped to receive and locate the lower end of the associated hook leg 32, thereby functioning with its companion supports 33 to support the housing and its associated mechanism.

As shown, the mounting plate 18 is provided with three elongated slots 38a positioned circumferentially of the plate to receive the upper parts of the hook members 29, and the walls of the cups 34 are provided with recesses 38b for receiving the hooks, as more clearly shown in FIG. 3.

I provide between the lower end of the sleeve 14 and the upper end of the housing 1 a radial fluid and vibration seal. For this purpose I provide a flexible sealing ring 39 in the radial space between the sleeve and the housing as shown in FIGS. 1 and 2, and as shown in FIG. 1 the ring 39 is generally in the form of a U in transverse cross section. The outer leg 40. of the U ring 39 is fitted around the outer surface of the upper end of the housing 1 and it is rigidly secured to this end by a clamping ring 41. The nexus of the U extends inwardly toward the sleeve 14 and terminates in an inner leg 42 which is pressed with a force-fit into a liquid-tight engagement with the sleeve 14 by the resiliency and undersize of the ring with respect to the size of the sleeve; this action may be reinforced by a garter spring 42a. Preferably and as shown the lower end of the leg 42 will be reinforced by a thickened circular rib 43. And preferably and as shown in FIG. 6

the inner surface of the leg '42 will be provided with a series of spaced circular sealing ribs or rings 44 to insure a liquid tight seal with the sleeve 14.

In View of the foregoing construction, it will be understood that the three elastomeric supports 33 and the sealing ring 39 arranged in parallel relation constitute vibra tion insulating means between the housing 1 and the sleeve 14 and sink. The members 33 yield downwardly to some extent with the weight of the disposal housing 1 and associated apparatus as shown in FIG. 3 thereby yieldingly to support the comrninuting means. While an elastomeric material in a technical sense may be construed to be a non-yieldingspring, it will be observed that the volume of each cup 34 is sufiiciently large to permit the body 33 to deflect to allow in turn the seat 38 and hook end in it to deflect downwardly and the seat to'tilt. Thus each support'33 mounts its rigid hook seat 38 so that it may tilt in any plane, and thus take a position in any plane to which it is forced by its associated hook 29. The three elastomeric supports 33 permit the housing 1 and associated mechanisms to tiltin any plane, and thus to vibrate in any plane, and this may be done without in any way affecting the liquid seal effected by the ring 39 which yieldingly maintains the seal while the housing 1 moves relative to the sleeve 14. Therefore, the support means 33 and sealing ring 39 isolate the vibration of the housing 1 and associated mechanism from the sleeve 14 and the sink '13 and hence from the house in which the sink in installed; Since the vibration is isolated the noise incident to vibration eifectis eliminated. Thus, it will be interference the sealing ring 39.

Itwill be observed that the sealing ring 39functions solely as a radial seal and vibration insulation member, and that it does not take any of the load of the machine supported from the sleeve 14.

It will be understood that in assembling the apparatus in the field, the sleeve 14 will be inserted through the sink opening 12. into its operative position; the gasket 24 and the clamping ring 23 will be elevated over the sleeve to their positions under the sink; and then the supporting ring 18 will be placed about the sleeve 14, and the snap ring 21 positioned over the head 22. After all of this the sleeve 14 will be clamped to the sink by threading the bolts 20 upwardly.

It will be understood that the ring 25 and the sealing ring 39 will have been assembled with the housing 1 at the factory.

In the field, the housing 1 with the attached support ring 25 and sealing ring 39 placed in position on the upper end of the housing will then be assembled with the mounting ring 18 by placing the housing in a vertical position under the sleeve 14- and elevating it so that the hook members 29 are received in the elongated openings 3801 provided in the ring 18. After the assembly has been moved upwardly so that hook ends 32 are above the level of the seats 38, the housing assembly is turned slightly to bring the lower ends of hook legs 32 into registry with their seats 38 and then the assembly is allowed to all so that these ends are received in interlocking relationship with their seats. The reverse operation will disassemble the housing from the sleeve 14-. I

It will be understood that when the housing 1 is elevated as the first step in the assembly of the housing with the sleeve 14- that it will carry the sealing ring assembly 39 up with it, as shown in FIG. 6. And that as the housing 1 is moved up the sealing ring automatically will be moved into sealing relation about and over the sleeve 14 as shown in FIG. 1. When the housing is removed, the sealing ring of course will be removed with it. Thus the comminuting apparatus is sealed and unsealed by the acts of assemblying the housing 1 with the sleeve 14 and disassembling it therefrom. The ring while it fits the sleeve sufiiciently tight to effect a liquid-tight seal during operation of the cornmintuing apparatus, will slip with respect to the sleeve 14 when the housing 1 is turned for assembly and disassembly.

The ring 25 will be provided with enlarged notches 45 to insure clearance of the ring 25 with the screws 20 while the housing 1 is being assembled with the sleeve 14.

The form of the invention shown in FIGS. 7 and 8 is like that shown in FIGS. 1 through 6 except that the supporting the hook-shaped members and their coacting resilient cylindrical members are reversed so that the hook members become the supporting parts attached to the sink supported sleeve and their coacting elastomeric members are attached to the comminuting housing. As shown in FIGS. 7 and 8, this modification is provided with a food waste comminuting housing 46 which corresponds to housing 1 and which like housing 1 houses the comminuting means and the comminuting means operating motor, all of which elements may be identically the same as shown in FIG. 1. Housing 46 is supported by sink bottom 47 by means of sleeve 48 of the same construction as is sleeve 14 of FIG. ;1; it is provided with a flange 49 resting on the sink bottom and it is clamped to the sink by means of bolts 50 threaded in a mounting ring 51 encircling sleeve 48 and abutting against a snap-ring 52 supported on the sleeve 48. The bolts bear against a clamping ring 53 to clamp the sleeve 48 to the sink; as in FIG. 1 a ring gasket 54 is interposed between the ring 53 and the sink bottom.

In this form of the invention the housing 46 and its associated comminuting mechanism is supported by three upright rod-like hook members 55 rigidly attached as by screw fastening means 56 to the ring plate 51. The hook members are spaced substantially 120 apart and as shown, have their nexus 57 lying generally circumferentially of the ring 51. The mounting means for housing 46 also includes a support ring 58 encircling the upper end of the housing and attached to it as is ring 25 attached to housing 1. Formed in the ring are three inverted cup-shaped parts 60 complementary to the hook ends 61 of members and into which these hook ends protrude. Inserted in each cup is an elastomeric cylinder 62 having a flange 63 at its lower end. Each member 62 has its upper end cemented or glued or otherwise bonded to the end wall of its associated cup section There will be cemented to the lower end of each member 62 a rigid metallic seat 64 having a central seat depression for the reception of the free end of the hook member 55, as shown. The cup member is provided with a slot 65 in one side wall and the ring 58 is provided with an elongated circumferentially extending slot 66 for the reception of the hook member.

A radial seal 67 of identically the same construction as the radial seal 39 of FIGS. 1 through 6 is provided, this seal also being reinforced by a garter spring 68.

The comminut-ing housing 46 is assembled with the sleeve 48 as in the first form of the invention. Thus, it is brought into alignment with the sleeve 48, elevated to a position at which the elastomeric members 62 are elevated above the ends of the hook ends 61 and then it is turned sufliciently to bring these members into alignment and finally allowed to fall so that the elastomeric members 62 rest upon the hook ends thereby to support the housing 46. When assembled the flexible member 67 as in the first form of the invention is automatically brought into sealing relation with the sleeve 48.
